Show original supplier description
The Air Flow Research AFR-1341 Enforcer is a pair of Small Block Ford (SBF) cylinder heads built with Permanent Mold “As-Cast” Technology. This technology ensures accurate and repeatable port location and performance across the intake runners, exhaust runners, and combustion chambers. These heads are designed for 302 to 363 cubic inch engines that operate below 6000 RPM, offering a budget-friendly upgrade. Key features include 185cc intake runners, a 64cc combustion chamber volume, and 1.900" intake valves, which are compatible with OEM piston valve relief. They also utilize one-piece 8mm 21-4N stainless steel valves, machined bead valve locks, hardened spring cups, and ductile iron valve seats. The heads have 1/2" head bolt holes and include 7/16" bushing adapters for use with stock 5.0L blocks. Standard valve springs are installed for non-Hi-Rev camshaft applications. These AFR Enforcer cylinder heads are compatible with specific engine codes, including B21, B31, N21, N41, and N412.
